Nissan Stanza race car – A tribute to SA motorsport’s glory days
The Jacobs brothers live and breathe everything Datsun and Nissan. Riaan Jacobs of The Datsun Shop in Mpumalanga shows us his 1982 Nissan Stanza race car tribute.
“We built this Stanza as a tribute to the 1982 Castrol 1000 and the car raced by Dick Sorensen and Barry Powers. It came out tops in Class C. It has been a lifelong passion to build this car. We searched far and wide to get the right donor car to start this project.”

To call it a mere “replica” race car doesn’t completely do this project justice, as Riaan Jacobs did find a host of period-correct parts that he built into this machine.
“Most of the parts are from a period-specific Stanza. I searched for about 6 years before I finally found a car in Windhoek, Namibia. We bought it at a pawn shop and towed it back to South Africa,” says Riaan.
“These cars were built ‘very rough’ back in the day, and they were built to go fast. Overall, it took me around 3 years to build the Stanza race car. A lot of work to the body was needed, such as the fitment of the wide wheel arches, the unique front fenders and the bumper.
“We had to respray the entire car and fit the engine. Thankfully, the gearbox was already there. When we got the car, it was little more than a rolling shell, and we had to start from scratch.
“The wheels had to be refurbished, which I did myself,” Riaan adds. “In fact, I did about 90% of all the work on the car. The L18 engine of the Stanza race car had to be rebuilt, plus the wiring also had to be replaced. We tried to make this engine as period-correct as possible. ‘Uncle’ Dick Sorensen is a very good friend of mine, and he gave me all the info from his original textbooks and even the dyno graph.”

“This information was immensely valuable. We used that info to keep the engine as close to period-correct spec as possible. We had the car on the dyno when it was finished, and it made 4 kW and 11 Nm less than the original motor. We think that might be due to our lower 10.5:1 compression ratio. We also use 95 octane fuel because that makes the car easier to run and maintain.
“The front suspension is completely rose-jointed, for maintenance, as well as for handling and feedback on track. The 3-link rear suspension is complemented by a limited-slip differential. We also did a disc-brake conversion on the rear axle, and the entire rear suspension has also been rose jointed.
“There is a 25-litre fuel tank with 2 pumps, and the roll-cage is an FIA-specification unit. The racing seat is not some modern unit, but is Martin Richards’ original seat, which he used in his first race car during oval track racing in Goodwood, Cape Town. I’m very sentimental about this car, in that regard.
“The livery that we chose was one of the most beautiful liveries of the ‘Eighties. I think the car only competed in 3 races with this livery. Some of the challenges involved finding the correct grille and rear lights. We had no luck whatsoever finding badges, so we decided to have them made by a specialist.
“Instead of having stickers printed, we at The Datsun Shop prefer to have the correct livery painted on. It is quite something to see a specialist painting for a day or two to get all the sponsor logos right.
“We will build a new engine for the car in the future, as we got our hands on a period-specific engine that is untouched. We have raced the car once since it was finished, at the Passion for Speed in 2021.
“The Stanza race car is quite a handful, and it was the 1st car I’ve owned with semi-slicks, but with every outing you learn more about the car, its setup and sensitivities to tyre temperatures and pressures. We would like to do 3- and 5-hour endurance races if those race meetings aren’t too far away from here.
“We are very family-oriented, and on weekends, my kids join me at the workshop and play and help me around the cars. We grew up with oval-track racing, as well as with Nissans and Datsuns. Through all of this and a 140Z I found and had to rebuild, I landed myself in this ‘total Z craze’. These 140Zs are my favourite Datsuns, partly owing to their rarity, but also their motorsport pedigree.
“My brother says that sometimes it is more fun building a car than driving it,” Riaan concludes.
It seems more builds are sure to pass through the Jacobs brothers’ hands in future. We wish them well!
